The Need for NG Optical Transport
Higher bandwidth driven by 3-play, WL data and
Business applications
Next Generation Optical (NGO or NG WDM)
The time is right for NG optical transport
New high speed interfaces (10GbE, 40G) introduced by
Data equipment
Limited flexibility, costly maintenance
Complicated operation with manual intervention
Emerging optical technologies
OTN & ASTN Standards

Expectations of ROADM
“SONET like” transport Wavelength assignment & reassignment
Simplifies the planning process Removes need to predict future traffic flows
Minimize operations - OPEX savings Remote provisioning and reconfiguration Software-tunable components Automatic power balancing / Equalization
Enable complex optical topologies Subtending ring closure Multi-ring closure Mesh topologies
